The comet ISON (or C/2012 S1, also known as Comet Nevski–Novichonok) was discovered on 21 September 2012 by Vitali Nevski (Belarus) and Artyom Novichonok (>Russia)

250px-ISON_Comet_captured_by_HST,_April_10-11,_2013The comet will be very close to Sun on Nov. 28. Scientists and skygazers are interested in knowing what will happen to it? There are 3 possibilities

1.       If it’s tough enough to survive the passage of the sun, we’ll get to see it with naked-eye in the early morning sky in the first week of December. 

2.       The sun could actually pull it apart.  So it becomes several chunks rounding the sun and putting on a great show again in early December

3.        If the comet is very weak, it could break up into a cloud of dust and be a complete bust in December.

The comet iscoming from the very edge of our solar system so it stills retains the primordial ices from which it formed four-and-a-half billion years ago.  It’s been traveling from the outer edge of the solar system for about five-and-a-half million years to reach us in the inner solar system.
